Use alexa on linux

[Linux for blind general discussion]

Snap packages don't generally break accessibility, and the fact that 
text mode packages can be distributed via snapd does make it a bit more 
attractive for some than flatpak, even with the drawbacks of having to 
mount a loopdev for every package, along with the implementation being 
so completely sandboxed that it is impractical if not impossible to 
share dependencies between packages. That said, different snapd 
implementations do tend to work somewhat differently for some reason, 
and many of the newer versions seem to be breaking accessibility of 
graphical packages, making it hard to recommend distribution via that 
method.
